Cut and clean faster with engineered blends

GMA stands at the forefront of abrasive blasting media development. While traditional slag blasting abrasives have changed very little for more than 50 years, the GMA Garnet™ blasting abrasives range is engineered to cut and clean faster, removing coatings quickly, and producing the cleanest surface to ensure the highest coating integrity. That's why maintenance teams globally choose GMA Garnet™ - the most advanced garnet abrasive.

Better surface integrity starts with GMA Garnet™

Traditional abrasive blasting media are one-dimensional, typically made of either coarse or fine grains. GMA's engineered blends are formulated with both coarse and fine grains to cut and clean. They deliver fast and effective coating or rust removal, leaving the cleanest surface ready for inspection and coating application.
